OK folks, I recently watched Dune (the version with Sting) and remembered something that has puzzled me for a long time. In the scene where the Baron Harkonnen is joyously celebrating his victory over the Atreides, one of his henchmen is doing something weird. The henchman is holding some kind of ornate black box with a big knob on the side. With a look of rapturous pleasure, he’s strenuously adjusting the knob while some strange sound emerges from the box. What the heck is going on? At first I thought he was remotely torturing some poor atreides soldier and the sound was the highly distorted screaming. But then I remembered that in the book, one of the Barons head guards is addicted to some drug that uses bizarre music as a component. So that may be what David Lynch was trying to portray.
